It’s not just Republicans who are hopping mad about the Internal Revenue Service singling out conservative groups for extra scrutiny on their 501(c)(4) status.

“No group or individual should be targeted by any government agency based on their political beliefs,” said Rep. Gene Green, a veteran Houston Democrat.

Green harkened back to the Watergate scandal, when President Richard Nixon ordered the IRS to make life difficult for journalists and political figures he believed were out to get him.

“This reminds me of the so-called ‘enemies list’ from the 1970s,” Green said today.

While Green was a rare Democratic lawmaker to express concern about the unfolding IRS scandal, Texas Republicans were united in outrage. Rep. Kenny Marchant, a Carrollton Republican, hailed House Republican leaders for scheduling a House Ways and Means Committee oversight hearing on the subject for this Friday.

“I have long been concerned with reports that the IRS has unfairly targeted some political groups over others — a charge that they have repeatedly denied,” said Rep. Kenny Marchant, a Carrollton Republican. “The IRS’s actions are unacceptable, and I commend [committee] chairman Dave Camp and Oversight Subcommittee chairman Charles Boustany for moving forward with a full investigation. We will continue to work to ensure there are protections in place so no American, regardless of political affiliation, has their right to free speech threatened by the IRS.”

Marchant last year sent IRS Commissioner Doug Shulman a letter demanding an explanation of IRS treatment of conservative groups. Here’s a copy:
